Description
VitraPOR® glass filter plate, 160 mm diameter, porosity 4, is a sintered disc made from borosilicate glass 3.3 for laboratory and process filtration. Nominal thickness is 13,0 mm with a tolerance of ± 3,0 mm; the surface is untreated and the plate is round and centred for clean seating in holders, funnels and custom assemblies. Offered as one piece from manufacturer ROBU - Stereon, the disc brings the chemical resistance and thermal behaviour typical of borosilicate 3.3 into filtration setups that need a defined porosity grade. Porosity 4 supports controlled retention and flow in analytical, preparative and routine workflows across chemistry and related laboratory environments. The untreated sintered face leaves conditioning and mounting choices to the user, while the centred round geometry aids alignment during installation. Suitable for integration into glassware and filtration apparatus where a robust, dimensionally specified filter plate is required, this VitraPOR® component provides a clear, standardised format for everyday and specialised filtration tasks without added surface finishes.
This article is part of Sintered glass filter plates & discs, in Filtration.

Questions about Filter Disc, centered, 160 mm, Por. 4 Thickness 13 mm ± 3.0 mm
What is this article?
Filter Disc, centered, 160 mm, Por. 4 Thickness 13 mm ± 3.0 mm is the article on this page. Luminix Health distributes ROBU - Stereon for laboratory use. It sits in Sintered glass filter plates & discs, inside Filtration, in Lab consumables.
A sintered glass filter is a disc of fused glass particles with a porosity grade, often 0 to 5, from coarse to fine. It is cleaned and reused. The porosity number, not a micrometre guess, is the specification. Hydrofluoric acid and strong alkali attack the glass.
Filtration holds back what is larger than the pores and lets the rest through. Paper is the ordinary laboratory filter. A membrane has a stated pore size and a polymer that must survive the solvent. A syringe filter is that membrane in a housing on a syringe. Glass fibre takes a higher dirt load. Ultrafiltration holds back macromolecules and passes salts. The pore size, the chemical compatibility and the volume are the three choices. Laboratory apparatus around filtration is indexed under ISO laboratory apparatus.
